CVE-2025-62970
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMissing Authorization vulnerability in Spencer Haws Link Whisper Free link-whisper allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Link Whisper Free: from n/a through <= 0.9.2.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Link Whisper Free WordPress plugin (versions <= 0.9.2) contains a missing authorization vulnerability that allows attackers to exploit incorrectly configured access control security levels. This likely permits unauthenticated or unauthorized users to access privileged link management functionality that should require higher privileges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate Link Whisper Free plugin installationCheck for the plugin directory at wp-content/plugins/link-whisper-free/ and locate the main plugin file (typically link-whisper-free.php) to read the version header commentAffected if The plugin directory exists and the version header shows a version number <= 0.9.2
-
Verify installed version from WordPress adminNavigate to WordPress admin dashboard > Plugins > Installed Plugins, locate Link Whisper Free, and confirm the version displayedAffected if The displayed version is <= 0.9.2 or no version number is shown (older installations may not display version)
-
Inspect plugin AJAX endpoints for authorizationExamine the plugin PHP files for AJAX action hooks (add_action with wp_ajax_) and check if they include capability checks (current_user_can) or nonce verification before executing sensitive link management functionsAffected if AJAX endpoints handling link creation, modification, or deletion lack current_user_can() capability checks or wp_verify_nonce() nonce verification
-
Test unauthenticated access to link managementSend a direct POST request to the plugin AJAX endpoint (typically /wp-admin/admin-ajax.php with action=link_whisper_*) without providing authentication credentials or valid nonce, then observe if the request is processed or rejectedAffected if The server returns a success response or processes the request instead of returning an authorization error (like 403 or 'You do not have permission')
A user is affected if Link Whisper Free version <= 0.9.2 is installed and the plugin's AJAX endpoints for link management are accessible without proper capability or nonce verification.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate Link Whisper Free to the latest version, or implement proper authorization checks (capability checks and nonce verification) on all sensitive functions and AJAX endpoints.
